The utility model relates to the technical field of cold chain transportation, in particular to an intelligent balanced refrigeration device for cold chain transportation, which comprises a cargo compartment, refrigeration equipment for conveying cold air into the cargo compartment, an automatic control device for controlling the refrigeration equipment and a cold air flowing device mounted in the cargo compartment, a compartment door facilitating loading is hinged to the end, away from the refrigeration equipment, of the cargo compartment in a matched mode, the automatic control device can automatically monitor the temperature of all positions in the cargo compartment and control automatic starting and stopping of the refrigeration equipment, the cold air flowing device comprises a cross-flow fan installed in the cargo compartment, and an air inlet and an air outlet are formed in the cross-flow fan. The cross-flow fan is installed on the lower side, close to a compartment door, of the cargo compartment, the cross-flow fan and the refrigeration equipment are arranged in an up-down diagonal mode, an air inlet of the cross-flow fan is horizontally arranged in the direction of a vehicle head of the cargo compartment, and an air outlet of the cross-flow fan is vertically arranged upwards. The refrigeration effect of the refrigerator car is improved.

This invention provides a battery pack sealing ring airtightness testing system, including a movable frame, a worktable, a sealing ring extrusion device, and an airtightness testing device. The worktable is located below the movable frame. The sealing ring extrusion device includes a pressure plate translation assembly, a pressure plate lifting assembly, and a pressure plate. The pressure plate translation assembly is mounted on the movable frame and can translate relative to the worktable on the movable frame. The pressure plate lifting assembly is fixed to the pressure plate translation assembly and has a pressure plate lifting end that moves vertically. The pressure plate is fixed to the pressure plate lifting end. In this invention, the sealing ring extrusion device can move and lift relative to the movable frame, realizing the mechanized movement of the pressure plate. This helps improve the adjustment accuracy of the pressure plate position and allows for stable movement of the pressure plate, avoiding manual movement of the pressure plate and potential collisions with the battery pack.
